QK2340T CNC pipe thread lathe

QK2340T CNC pipe thread lathe

Overview

QK2340T CNC pipe thread lathe has a tilting structure. The front and back ends of the machine tool spindle are made of domestic pneumatic or hydraulic chucks. The spindle bearings are ZWZ, HRB, NSK and other well-known domestic brands and imported brands. The upper tool post is a domestic eight-station. Electric tool post, the lower tool post is a fixed and fine-adjustable fixed tool post, the spindle motor is an explosion-proof asynchronous motor or the main servo motor, the numerical control system is a FANUC numerical control system, three-axis drive, and the front end is equipped with a centering and tensioning device, equipped with automatic Chip removal machine.

This machine tool is a large-scale special numerical control equipment used for petroleum casing thread and special thread processing for petroleum casing. It can also be used as a general CNC lathe. Surface, spherical surface, curved surface, and cuts. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
